5V here we go
First, Rocketct from Arudino posted a great comment: https://github.com/arduino/ArduinoCore-samd/issues/444#issuecomment-526636552 – which effectively confirms that the board CAN generate 5V without a USB cable, and indeed it’s just my missing resistor that caused my (days and days and days of) problems!
I’m chatting with Arudino support for a couple of replacements, and ordered a 3rd straight from the Arudino store (as opposed to Amazon UK). Watch this space!
CAD is not the real world
Here’s a snapshot of the first 3d printed version of the Pointer, the hits-per-minute meter:
Here’s a good tip: if you have a 10mm peg, it will not fit in a 10mm hole, at least, not if both are 3d printed.
From some quick research it looks like it’s a case of trial-and-error to find how much “extra” space to leave, and is very much dependent on the printer being used, and print settings.
I settled for ~0.15mm, which is a tight fit, but allows stuff to stick together pretty effectively. To avoid putting stress on prints I think 0.2mm is probably better.
Crowdsourcing AI training data!
After updating the BeatBrain collector mod to support uploading straight to an API, I thought I might try dropping some info and a link on the Beat Saber subreddit to see if one or two people might pick it up and share some data.
I also posted on the Beat Saber modding Discord, which got quite a lot of interest. As of a day or so later, here’s a chart of the number of recordings (more than a thousand!), number of different songs (399) and total users (25).
I’ve started digging around and researching options for the ‘blockchain’ aspect of the demo. Right now it feels like recording a history of recorded data and playthroughs onto an immutable ledger might be an idea to allow someone to build up a kind of “fingerprint” for their movement data (like a biometric?). This could tie into the ‘cybersecurity’ part of the demo, which could detect ‘fraudulent’ recordings..
